Abstract

Xp11 translocation cancers include Xp11 translocation renal cell carcinoma (RCC), Xp11 translocation perivascular epithelioid cell tumor (PEComa), and melanotic Xp11 translocation renal cancer. In Xp11 translocation cancers, oncogenic activation of TFE3 is driven by the fusion of TFE3 with a number of different gene partners; however, the impact of individual fusion variant on specific clinicopathologic features of Xp11 translocation cancers has not been well defined. In this study, we analyze 60 Xp11 translocation cancers by fluorescence in situ hybridization using custom bacterial artificial chromosome probes to establish their TFE3 fusion gene partner. In 5 cases RNA sequencing was also used to further characterize the fusion transcripts. The 60 Xp11 translocation cancers included 47 Xp11 translocation RCC, 8 Xp11 translocation PEComas, and 5 melanotic Xp11 translocation renal cancers. A fusion partner was identified in 53/60 (88%) cases, including 18 SFPQ (PSF), 16 PRCC, 12 ASPSCR1 (ASPL), 6 NONO, and 1 DVL2. We provide the first morphologic description of the NONO-TFE3 RCC, which frequently demonstrates subnuclear vacuoles leading to distinctive suprabasal nuclear palisading. Similar subnuclear vacuolization was also characteristic of SFPQ-TFE3 RCC, creating overlapping features with clear cell papillary RCC. We also describe the first RCC with a DVL2-TFE3 gene fusion, in addition to an extrarenal pigmented PEComa with a NONO-TFE3 gene fusion. Furthermore, among neoplasms with the SFPQ-TFE3, NONO-TFE3, DVL2-TFE3, and ASPL-TFE3 gene fusions, the RCCs are almost always PAX8 positive, cathepsin K negative by immunohistochemistry, whereas the mesenchymal counterparts (Xp11 translocation PEComas, melanotic Xp11 translocation renal cancers, and alveolar soft part sarcoma) are PAX8 negative, cathepsin K positive. These findings support the concept that despite an identical gene fusion, the RCCs are distinct from the corresponding mesenchymal neoplasms, perhaps due to the cellular context in which the translocation occurs. We corroborate prior data showing that the PRCC-TFE3 RCCs are the only known Xp11 translocation RCC molecular subtype that are consistently cathepsin K positive. In summary, our data expand further the clinicopathologic features of cancers with specific TFE3 gene fusions and should allow for more meaningful clinicopathologic associations to be drawn.

摘要

Xp11易位性癌症包括Xp11易位性肾细胞癌(RCC)、Xp11易位性血管周上皮样细胞瘤(PEComa)和黑素性Xp11易位性肾癌。在Xp11易位性癌症中,TFE3的致癌激活是由TFE3与许多不同基因伙伴的融合驱动的;然而,个体融合变体对Xp11易位性癌症特定临床病理特征的影响尚未明确界定。在本研究中,我们使用定制的细菌人工染色体探针通过荧光原位杂交分析了60例Xp11易位性癌症,以确定其TFE3融合基因伙伴。在5例病例中还使用了RNA测序来进一步表征融合转录本。这60例Xp11易位性癌症包括47例Xp11易位性RCC、8例Xp11易位性PEComa和5例黑素性Xp11易位性肾癌。在53/60(88%)的病例中鉴定出了融合伙伴,包括18例SFPQ(PSF)、16例PRCC、12例ASPSCR1(ASPL)、6例NONO和1例DVL2。我们首次对NONO-TFE3 RCC进行了形态学描述,其经常表现为核下空泡,导致独特的核上栅栏状排列。类似的核下空泡化也是SFPQ-TFE3 RCC的特征,与透明细胞乳头状RCC有重叠特征。我们还描述了首例具有DVL2-TFE3基因融合的RCC,以及一例具有NONO-TFE3基因融合的肾外色素沉着性PEComa。此外,在具有SFPQ-TFE3、NONO-TFE3、DVL2-TFE3和ASPL-TFE3基因融合的肿瘤中,RCC通过免疫组织化学几乎总是PAX8阳性、组织蛋白酶K阴性,而间充质对应物(Xp11易位性PEComa、黑素性Xp11易位性肾癌和肺泡软组织肉瘤)则PAX8阴性、组织蛋白酶K阳性。这些发现支持了这样一种概念,即尽管基因融合相同,但RCC与相应的间充质肿瘤不同,这可能是由于易位发生的细胞环境所致。我们证实了先前的数据,表明PRCC-TFE3 RCC是唯一已知的始终组织蛋白酶K阳性的Xp11易位性RCC分子亚型。总之,我们的数据进一步扩展了具有特定TFE3基因融合的癌症的临床病理特征,应该能够得出更有意义的临床病理关联。
